摘要
提出了在周期极化LiNbO3 光学参量振荡 (PPLN OPO)中伴有四波混频 (FWM )的发生 ,论述了PPLN OPO中的抽运光λ3 (10 6 4nm) ,信号光λ1(15 0 0nm) ,闲频光λ2 (36 6 0 5 5nm) ,信号光λ1的倍频光λ4(75 0nm) ,满足FWM的频率匹配与准相位匹配的条件 ,初步建立了PPLN OPO FWM的过程理论体系 ,进行了光学系统装置的实验 。
The generation of FWM going with PPLN-OPO was put forward for the first time. FWM frequency matching and quasi-phase matching conditions of bumping wave λ 3 (1064 nm), signal wave λ 1 (1500 nm) and idle wave λ 2 (3660.55 nm) in PPLN-OPO was discussed. The system of PPLN-OPO-FWM process was set up theoretically and the setting of optical system was realized experimentally. The conclusion of experiment was accorded with theoretical analysis, which is valuable for the study of PPLN, OPO and FWM in theory and practice.
